Granular NPK Complex Fertilizer

 

Spreader setting

Broadcast fertilizer spreader

A (lbs/acre,) x C (ft) x D (ft) ÷ 43560 = B (lbs)
A (kg/ha) x C (m) x D (m) ÷ 10,000 = B (kg)
 
A = application rate (desired rate lbs/acre or kg/ha);
B = weight of fertilizer (lbs or kg) collected from spreader
in sixty seconds;
C = distance traveled (ft or meter) in sixty seconds;
D = swath spacing width (ft or meter)
 
 
Drill type fertilizer spreader
A (lbs/acre) x C (rev) x D (ft) x E (ft) ÷ 43560 = B (lbs)
A (kg/ha) x C (rev) x D (m) x E (m) ÷ 10,000 = B (kg)
 
A = application rate (desired rate lbs/acre or kg/ha);
B = weight of fertilizer (lbs or kg) collected from
applictor(s) from one row during C- revolutions;
C = number of revolutions of drive wheel;
D = “actual” drive wheel circumference (feet or meter)
E = row spacing (feet or meter).
